Preparation method of environment-friendly continuous casting tundish dry material
The invention relates to the technical field of preparation of continuous casting tundish dry materials, and provides a preparation method of an environment-friendly continuous casting tundish dry material, which comprises the following ingredients and a binding agent: the ingredients select medium-grade magnesia particles and fine powder as raw materials, and the ingredients are prepared according to the following formula in percentage by weight: 95.31% of MgO, 1.22% of CaO, 2.02% of SiO2, 0.80% of Fe2O3 and 0.65% of Al2O3; the binding agent is a mixture of thermosetting phenolic resin powder, glucose and polyvinylpyrrolidone; according to the invention, polyvinylpyrrolidone is adopted as a binding agent of the dry material for the continuous casting tundish, and can interact with the surfaces of various materials to generate relatively strong adhesive force, so that various components are effectively bonded together, and the durability and stability of the dry material are favorably improved; compared with the prior art, the magnesium tundish dry material has the advantages that environmental pollution and health hazards to operators can be reduced, the normal-temperature strength of the magnesium tundish dry material is higher than that of a glucose-combined magnesium tundish dry material, the slag resistance of the magnesium tundish dry material is better than that of the glucose-combined magnesium tundish dry material, and the overall using effect is remarkably improved.
本发明涉及连铸中间包干式料的制备技术领域，提出了一种环保型连铸中间包干式料的制备方法，包括以下配料和结合剂：配料选用中档镁砂颗粒和细粉为原料，按以下重量百分比计的配方配料：MgO 95.31％、CaO 1.22％、SiO22.02％、Fe2O30.80％、Al2O30.65％；结合剂为热固性酚醛树脂粉、葡萄糖、聚乙烯吡咯烷酮的混合物；本发明通过采用聚乙烯吡咯烷酮作为连铸中间包干式料的结合剂，能够与多种材料表面发生相互作用产生较强的粘附力，有效地将各种组分粘结在一起，这有助于提高干式料的耐久性和稳定性；能够减少对环境的污染和对操作人员的健康危害，且其常温强度大于葡萄糖结合的镁质中间包干式料，而其抗渣性能则优于葡萄糖结合的镁质中间包干式料，整体使用效果显著提升。
